HAY-PRESS.

SPECIFICATION formingpart of Letters Patent No. 269,659, dated Decemlcer 26, 1852.

Application filed November 15, 1882. (ModeL) To all whom it may concern Be it known that I, FRANKLIN FREY, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Hay-Presses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a hay-press having superior construction in the bale-chamber,'sweep, and lever mechanism.

The nature of my invention will appear in the following description of the above parts and their necessary connections.

Figure l is a side view, showing the position of the parts when the follower is forced fullyin to press the hay. Fig. 2 isa plan view, showing the position of the parts under like circumstances. Fig. 3 is-a plan view, partly in broken section, showing the position of the sweep and lever mechanism when the sweep has been carried forward to retract the follower. Fig. 4 is a detail view of the sweep and yoke. Fig. 5 is a detail view showing the mannerof locklngthe sweep when drawn back.

Like letters refer to like parts in the drawings.

The press is mounted on wheels, so that it can be moved from place to place. The main frame-work consists of two lower beams, A B, resting on the trucks, and the upper beams, G D, separated from the lower by the standard E, the outer end, F, of the bale-chamber, and the intermediate supports, the whole being suitably bolted together at intervals to give necessary strength. (See Figs. 1 and 3.)

The bale-chamber is at the forward end of the press, the floor and end being solid and immovable. The end F is strengthened in front by horizontal bars of metal a a, which are prevented from bulging out by the bolts 1) b passing from the lower beams to the upper. Furthermore, the middle bar is fastened by a staple driven into the end of the-bale-chamber, and the upper and lower bars are fastened to the cross-ties between the beams.

The sides of the chamber are formed by doors G G. These doors are hinged upon cliued bridges b b, carrying a latch, t. On the inside of the doors are placed metallic hooks h h, for retaining the hay in the balechamber and preventing it from slipping bolts 1) b, and provided on theoutslde with inback while the follower is at work. When the press is in operation the doors are closed by slipping the bars H H, hinged to the beams, upon the inclined bridges, and fastening them there by the latches t,- bnt when a sufiicient amount of hay has been pressed said doors are easily opened for putting on the ties and removing the bale.

At the top of the bale-chamber is placed a pressure-relief door, I. This door is fastened inthe same way as the side doors, but is shorter, has a cross-bar, c, to prevent it from falling inward, and is hinged to the bolt d, be-

tween the upper beams, at a distance farther back than the side doors are, in order to withstand the upward pressure the better.

Behind the door I is arranged the hopper J for feeding the hay to the bale-chamber when the follower is retracted; but as said hopper is of an ordinary construction it will not be described. 4

At the side of the press, as shown, and extending nearly to the rear, is constructed a strong frame. Extending out from this are two triangular metallic supports, 0 c, forming a journal for the vertical metallic axle K. Up-

also with a sliding spring-bolt, k, engaging at one end with the recess 9 of the yoke and curving up at the other end to engage with a hinged lever, l, on the top of the sweep; also with a hinged hook, at, engaging with a curved lever, a, attached to the side frame. (See Fig. 3.) The lever n has a projection, 0, at one end to fit into the hook m; but the other end is cned outand the follower driven home.

curved inward topropcilv engage with the knuckle-joint to quickly throw said joint out of the dead-centerand retract the follower.

The standard E has firmly fixed thereto a guide, 1), for the sweep. and an arm, 1', for actuating the lever Z at the top of the sweep. The. shape and arrangement of the guide and arm are shown in Figs. 2 and-5. The guide may support the curved lever also.

From the end of the hook h in the yoke the chain N connects the sweep with the knucklelever 0. This lever, which may also he called the operating-lever,?is composed of two arms, s 8, one pivoted to the standard E, the other to the rear extension ofthe follower. They are joined at the center through theiroverlapping reduced ends of metal by a pin. Thus the arms are easily bent and straightened.

The inner portion of the follower is made solid, and has its face 'irovided with grooves to correspond tothose opposite in the end of the hale-chamber, so that ties may be easily applied. The outer end of the follower is made hollow to give ieady attachment to the inner arm of the. knuckle-lever and to give play to the same. This construction also guides and steadies the follower.

The operation of the press is, briefly, as follows: The sweep is carried forward by the team until the sliding bolt ot' the sweep engages with the yoke carrying the leverchain. The sweep is then carried back until the hinged hook looks with the curved lever, and the hinged lever sliding upon the inclined face of the fixed arm releases the springbolt. Bythistimetheknuckle-leveris straight- \Vhen the sweep starts forward the yoke and leverchain swing free, and the sweep has to act on the curved lever only. Almost at the same time the hinged hook draws the curved lever inward, throwing the knuckle-lever at once out of the (lead-center and quickly retracting the follower. When this has been done the hinged hook passes clear of the outer end of said curved lever and the sweep goes forward free of all strain until the spring-boltagain engages with the yoke to repeat the operation.

lhcadvantages of my press will appear from the above. By passing the chain from the yoke about the side and end of the sweep great and steady power is given the knucklelever, while the disk and groove give support and guidance to the chain. After the yoke engages the sweep the power is not applied to the chain until the. sweep has passed nearly to a right angle with the side of thepress, giving a. quick motion and great force. However, this may be varied by lengthening or shortening the chain. nnshipping of the yoke the men are saved labor and speed is gained; also, the sweep is released from strain on the forward movement. The knuckle-lever being quickly bent by the curved lever, the follower 1s retracted at once, as it were, and the men are given nearly dou- By the automatic shipping and ble the ordinary time to feed hay. Hence they can feed more hay at one charge than formerly, and the bale will be formed more rapidly.

Ilavingfully described my invention, what I claim is- 1. The sweep having a metallic supportingdisk and guiding-groove at the end thereof, as shown, combined with the operating-lever and follower, substantially as set forth.

2. The combination of the sweep and yoke, with the operating-lever and follower, as set forth.
